Boundless Blocks
by Neuromuser
Boundless Blocks lets players craft building blocks that are never used up once they exist, so large projects can keep going without stopping to collect more material.
What it does
Players craft an infinite version of a building block by combining nine stacks of the same block in the crafting grid. The infinite block is placed like any other block, but placing it no longer consumes anything. Shift and right-clicking with an infinite block returns a normal block of that type, so the infinite block can be used as a stock source. Which blocks are supported and how many items each recipe needs can be set in the config, and a blacklist filled with keywords can exclude blocks from the system, for example default ores that would otherwise be too overpowered to make infinite.
The mod is aimed at creative building and large-scale projects, where gathering materials becomes the main obstacle. It is a Fabric mod and is published for 1.19.2 – 1.21.10 in nine release versions. Client and server are both needed: the mod must be installed on the server and on every client that joins it. Boundless Blocks is open source under the MIT License, and its source code and issue tracker are public.
Key features
Infinite block crafting
Nine stacks of the same block are combined in the crafting grid to produce its infinite counterpart.
Non-consuming placement
Placing an infinite block takes nothing from the inventory, so construction is not interrupted by a shortage.
Normal blocks on demand
Shift and right-clicking an infinite block yields a regular block of that type when one is needed.
Configurable supported blocks
The list of supported blocks and the amounts required per recipe can be adjusted in the config.
Keyword blacklist
Blocks matching chosen keywords are excluded from infinite crafting, so specific groups such as default ores stay out of the system.
